MRI Q/A outcomes.A) Histograms of the median frame wise displacement of the subjects who attempted scans. The blue bars represent those who passed and the orange bars represent those who failed. B) Each plot shows for each gradient direction (represented by a line in 3D), the percentage of participants (represented by the color of the line) with data of sufficient quality as detailed in Supplementary methods. The plot on the left illustrates the group failing, the one on the right those passing DTI Q/A (n = 30 and n = 28, respectively).
